Among them P. pseudovermiseta does not, belongs to this genus becquse the most significant characters: number of, aggenital setae and the position of the adanal setae are different. I think it belongs to the genus Perxylobates Hammer, 1972 (comb.nov.). The other species may be distinguished by the following key: 1 ( 4) Lamellar setae originating far from lamellar cuspis. Sensillus not dilate distally. 2 ( 3) Sacculi Sa slit-like schauenbergi Mahunka, 1977 3 ( 2) Sacculi Sa round bérlései Bhattacharya, 1980 1 * 4 ( 1) Lamellar setae arising on or very near to lamellar cuspis. Sensillus dilated distally. 5 ( 6) Between the sejugal and third apodeme a strongly chitinized semicircular formation present. Median part of coxisternal region with a wide, framed field, without apodemes or borders (Fig. ) monstruosa sp.n. 6 ( 5) Median part of coxisternal region normal, semicircular formation absent. 7 ( 8) Five pairs of genital setae present. Sejugal and third apodemes compose a transversal ones in front of genital aperture. Lamellae short, rounded laterally xena Mahunka, 1977 8 ( 7) Six pairs of genital setae present. No transversal apodeme in front of genital aperture. Lamellae elongated anteriorly punctulate Bal. et Mah.,1967 *The form of sensillus is slightly variable, the type specimen of P. scnauenbergi has also bacilliform sensillus as has P. bérlései , consequently, the two species may be identical. The sculpture of notogaster is not a specific character. The form of sacculi and the measurement do not seem to be enough for the separation. The investigation of the type of P. bérlései would be desirable.
